Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to shoes and more particularly pertains to a new shoe having removable heels for permitting a user to wear a single pair of shoes which can be used in high heel form and in a flat form.

2. Description of the Prior Art

The use of shoes is known in the prior art. More specifically, shoes heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

Known prior art shoes include U.S. Pat. Nos. 4,219,946; 4,214,384; 4,805,320; 3,946,505; Des. 347,937; and 4,062,132.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new shoe having removable heels. The inventive device includes a sole having opposite heel and toe ends. The lower surface of the sole has a hole therein located towards the heel end of the sole. The hole has a perimeter with a number of sides. Each of the sides of the perimeter of the hole has an aperture into the sole. A heel is also provided and has a block outwardly extended from its upper end. The block also has a number of sides with each of the sides of the block associated with a side of the perimeter of the hole. The block is removably inserted into the hole of the lower surface of the sole and each of the sides of the block has a detent which are inserted into the aperture of their associated side of the perimeter of the hole.

In these respects, the shoe having removable heels according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of permitting a user to wear a single pair of shoes which can be used in high heel form and in a flat form.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new shoe having removable heels embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 4, the shoe having removable heels 10 generally comprises a sole 14 having opposite heel and toe ends 16,18. The lower surface 24 of the sole 14 has a hole 26 therein located towards the heel end 16 of the sole 14. The hole 26 has a perimeter with a number of sides. Each of the sides of the perimeter of the hole 26 has an aperture 28 into the sole 14. A heel 30 is also provided and has a block 32 outwardly extended from its upper end. The block 32 also has a number of sides with each of the sides of the block 32 associated with a side of the perimeter of the hole 26. The block 32 is removably inserted into the hole 26 of the lower surface 24 of the sole 14 and each of the sides of the block 32 has a detent which are inserted into the aperture of their associated side of the perimeter of the hole 26.

In closer detail, the shoe 10 has some sort of upper 12 and a sole 14. The sole 14 has a lower surface 24, opposite heel 30 and toe ends 16,18, and a pair of sides extending between the heel 30 and toe ends 16,18 of the sole 14. The lower surface 24 of the sole 14 has a hole 26 in it. The hole 26 has a perimeter, preferably generally rectangular in shape, which has a number of sides. Each of the sides of the perimeter of the hole 26 has an aperture 28 into the sole 14.

As illustrated in the Figures, the upper end of the heel 30 has a block 32 outwardly extending therefrom. The block 32 has a number of sides extending therearound which define the generally rectangular perimeter of the block 32. Each of the sides of the block 32 is associated with a side of the perimeter of the hole 26. The block 32 is removably inserted into the hole 26 of the lower surface 24 of the sole 14, preferably such that the heel 30 abuts the lower surface 24 of the sole 14.

Each of the sides of the block 32 has a detent which are inserted into their respective aperture 28 of their associated sides of the perimeter of the hole 26. The detents 34 are insertable into the apertures 28 for releasably engaging the perimeter of the hole 26 to help hold the block 32 to the sole 14. Preferably, each of the detents 34 comprise a ball and a spring with the spring located in the interior of the block 32 and the ball extending from its respective side of the block 32.

Preferably, the invention includes a generally rectangular U-shaped securing pin 36 having a pair of spaced apart elongate arms 38,40 connected by a cross member 42. The arms 38,40 of the securing pin 36 are removably inserted through a pair of bores 46 extending from one of the sides 20 of the sole 14 and into the hole 26 and the block 32 (preferably through the block 32 and into a distal side of the hole 26). The securing pin 36 is designed for helping securely hold the block 32 in the hole 26 of the sole 14. In the preferred embodiment, the cross member 42 of the securing pin 36 has an arcuate portion 44 extending in a direction opposite the arms 38,40 of the securing pin 36 such that the arcuate portion 44 outwardly extends from the side of the sole 14 when the securing pin 36 is inserted into the side of the sole 14. The arcuate portion 44 helps a user easily remove the securing pin 36 from the side 20 of the sole 14 with one of their fingers.

In an illustrative example for a typically sized women's shoe, the block 32 has a height measured from the heel 30 of less than about 3/4 inch, and a length and a width defined between the sides of the block 32 of 11/4 inches and 1/2 inch, respectively.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
